Roofs and Ceilings
A lot of opportunities are available in improving energy efficiency, safety, comfort, health and durability of the building. More so for either retrofitting existing ceilings, attics or building new ones. You have a lot of energy-related improvements in roofs and ceilings, which are categorized as: air leakage, insulation, and ventilation.
Old homes that were built before the 80s are relatively leaky and tend to be poorly insulated compared to the homes built today. An excellent opportunity to correct these flaws is a remodeling project. This gives one an excellent opportunity to reduce the leakage and upgrade the levels of insulation and reduce leakage of air at a more convenient and cheaper than retrofitting these items separately. This will depend on the type of work that you want for the project. Keep in mind that the worse the home is to start with, the more savings and other benefits possible.
There is the opportunity, however, with any new construction to design the structure to be more easily insulated. In this case, be sre to increase the levels of insulation, check the quality of the insulating work carried out, and assure air tightness.
